Software Version Description, Station Software 505.05 07/2008 Edition
5.12 Placement sequence for all heads
As of software version 505.xx, placement sequences are supported for all head types.
In order to achieve ideal placement performance, the placement sequence is generally calculated
and specified prior to optimization. If, however, components are to be placed above each other or if
the placement positions are very close together, the user can specify the placement sequence for
these components by changing the placement level. During the subsequent optimization of the
placement sequence, these definitions are taken into consideration and remain unchanged.
The specifications for the placement sequence are transferred to the station using the placement
program generated in SIPLACE Pro (file "aktuell.nu").
5.12.1 Restrictions
- The placement performance is no longer optimized if the placement sequence is specified in
SIPLACE Pro by defining placement levels.
- Only one placement level is placed in each head cycle -> reduction of placement performance.
- Version 505.xx of the software must be installed on all stations in the line.
5.13 Face-down recognition
When chip components are picked up, it is possible that individual components are picked up on the
underside by the nozzle. If the vision system detects this, the component is rejected in order to avoid
incorrect placement. The top and underside of the components must be clearly different in terms of
color in order to allow recognition of face-down (flipped) components.
The vision system determines the brightness level (possible values: 0 = dark through 255 = light) in
a rectangle in the center of the component.
- If the measured value is above the specified brightness threshold, the rectangle is recognized
as "light".
- If the measured value is below the specified brightness threshold, the rectangle is recognized as
"dark".
The value measured on the underside of the component is now compared with the specified
threshold. It is thus possible to determine whether the component was picked up with the underside
facing upward (i.e. flipped) or correctly.
The brightness threshold is either set manually or determined by teaching flipped components if the
difference in brightness between the two sides is low. It is also necessary to specify whether the top
side is darker or lighter than the underside.

Setting: it is light in the camera image
This setting is used for components where the upper side is lighter.
If the component is shown as light in the camera image, it is taken to be flipped and thus
rejected.
- Setting: it is dark in the camera image
This setting is used for components where the upper side is darker.
If the component is shown as dark in the camera image, it is taken to be flipped and thus
rejected.
5.14 Synchronous dual conveyor with PCB barcode
As of software version 503.01, the use of synchronous dual conveyors is supported. Software
version 505.01 now allows the use of synchronous dual conveyors with PCB barcode operation.
The following workflow/conditions also apply to PCB barcode operation:8
- Each board must have a barcode.
- The barcodes are read as the boards travel into the machine.
- Both barcodes are transmitted to the programming system which then selects the appropriate
recipe from the recipes configured. The panel information for this recipe is transmitted to the
station.
- If the programming system does not contain a recipe for the barcodes that have been read, the
boards are simply transported through the machine.
If the board has no barcode, or the barcode cannot be read, the station opens up a dialog box and
prompts the operator to enter a barcode by hand.
5.14.1 Restrictions
- No ink spot recognition
- No whispering down the line
- No "virtual ink spot" SOKO

5.15 Synchronous dual conveyor with OIS
Up to now, it was not possible to record board data for a board using OIS if the placement machine
was operated in "synchronous dual conveyor" mode. This is now possible for OIS Version 2.4 in
combination with Version 505.01.xx of the station software.
It can be achieved as follows:8
OIS creates one record in its database per physical board. This means that two records are created
if the placement machine is working in "synchronous dual conveyor" mode and one record is
created if the machine is working in "single conveyor" mode.
5.16 2D PCB barcode reader for all machines
Using version 505.xx of the software, the 2D PCB barcode reader can be used on all machine types
supported by this version. Version 505.xx of the software supports both 1D and 2D barcode types.
5.17 Station-by-station download
To keep product change times as low as possible, version 505.xx of the software allows you to
specify a new job for each station individually in the line controller (SIPLACE Pro Line Control). This
means that it is no longer necessary to empty the entire line.
1. To initiate the job change the operator must first specify a new job in the SIPLACE Pro Line
Control user interface with the "Stationwise Download" option. Station-by-station download
only works, however, if "Standard Mode" is set for downloading under Tools Æ
Configuration....
2. When the last board of the current job moves into the input conveyor of the first station in the
line, the operator must click the flashing "Change job by station" icon in the main view of the
station computer interface. The station is emptied. Then the changeover can be performed
and once the changeover process has been confirmed, the new job can be processed at this
station.
3. The procedure described in point 2 must be repeated for every other station in the line.
- Station-by-station download can be carried out for a station with a single conveyor or with a dual
conveyor in "asynchronous dual conveyor" mode with or without a setup change.
- After a station-by-station download operation has been canceled, a complete line download
must first be carried out.
